+# Prerelease Setup Guide
+
+## Overview
+
+This repository uses branch-specific prerelease channels for publishing packages from feature branches and fix branches. Each branch category gets its own npm dist-tag:
+
+- `fix/*` → `2.22.1-fix.1` (dist-tag: `fix`)
+- `feat/*` → `2.22.1-feat.1` (dist-tag: `feat`)
+- `beta` → `2.22.1-beta.1` (dist-tag: `beta`)
+
+Note: `chore/*` branches do not publish - they're for internal changes not meant for client distribution.
+
+## GitHub Environment Setup
+
+### 1. Create the Publish-Prerelease Environment
+
+1. Go to: https://github.com/segmentio/analytics-react-native/settings/environments
+2. Click "New environment"
+3. Name: `Publish-Prerelease`
+4. Click "Configure environment"
+
+### 2. Configure Branch Protection (Optional)
+
+Since semantic-release now controls which branches can publish based on `release.config.js`, you can either:
+
+**Option A: Allow any branch** (Recommended)
+
+- Leave "Deployment branches and tags" set to "All branches"
+- semantic-release will handle branch filtering
+
+**Option B: Restrict to specific patterns**
+
+- Select "Protected branches and tags only"
+- Add patterns: `fix/*`, `feat/*`, `beta`
+
+### 3. Add Required Reviewers (Optional)
+
+If you want manual approval before publishing:
+
+- Enable "Required reviewers"
+- Add reviewers from your team
+- Set wait timer if desired
+
+### 4. Add Environment Secrets
+
+The environment needs access to npm for publishing. You have two options:
+
+#### Option A: npm Token (Traditional)
+
+1. Generate an npm automation token:
+
+   ```bash
+   npm login
+   npm token create --type=automation
+   ```
+
+2. Add the token as a secret:
+
+   - Click "Add secret"
+   - Name: `NPM_TOKEN`
+   - Value: `npm_xxx...` (your automation token)
+
+3. Update the workflow to use the token:
+   ```yaml
+   - name: Release (prerelease)
+     run: |
+       BRANCH_NAME=$(git rev-parse --abbrev-ref HEAD)
+       devbox run -e GITHUB_REF=refs/heads/$BRANCH_NAME release
+     env:
+       GH_TOKEN: ${{ github.token }}
+       NPM_TOKEN: ${{ secrets.NPM_TOKEN }}
+   ```
+
+#### Option B: npm Provenance with OIDC (Recommended)
+
+The current setup uses npm provenance with OIDC, which doesn't require storing an NPM_TOKEN. This is more secure because:
+
+- No long-lived tokens to manage
+- Automatic provenance attestation
+- Built-in supply chain security
+
+**No additional npm setup needed!** The workflow already has:
+
+- `id-token: write` permission
+- `@semantic-release/npm` with `provenance: true`
+
+npm will automatically authenticate using GitHub's OIDC provider.
+
+**Requirements:**
+
+- The `@segment` npm organization must have publishing from GitHub Actions enabled
+- The package must be public or the org must be on a paid npm plan
+
+To verify OIDC is configured:
+
+1. Go to: https://www.npmjs.com/settings/segment/packages
+2. Check that "Publish" permissions include GitHub Actions
+3. If not, contact npm org admin to enable it
+
+## Testing the Setup
+
+### 1. Test with Dry Run
+
+```bash
+# From your feature branch
+gh workflow run release.yml -f type=dry-run --ref fix/your-branch
+```
+
+This will:
+
+- Run CI checks
+- Simulate the release process
+- Show what would be published (without actually publishing)
+
+### 2. Publish a Prerelease
+
+```bash
+# From a fix/feat branch
+gh workflow run release.yml -f type=prerelease --ref fix/your-branch
+```
+
+This will:
+
+- Run CI checks
+- Run E2E tests
+- Publish to npm with the appropriate dist-tag
+- Create a GitHub release
+
+### 3. Verify on npm
+
+```bash
+# Check dist-tags
+npm dist-tag ls @segment/analytics-react-native
+
+# Should show something like:
+# latest: 2.22.0
+# beta: 2.22.1-beta.1
+# fix: 2.22.1-fix.1
+# feat: 2.22.1-feat.2
+```
+
+### 4. Install a Prerelease
+
+```bash
+# Install a specific prerelease channel
+npm install @segment/analytics-react-native@fix
+npm install @segment/analytics-react-native@feat
+
+# Or a specific version
+npm install @segment/analytics-react-native@2.22.1-fix.1
+```
+
+## Troubleshooting
+
+### "semantic-release says no version will be published"
+
+Check that your branch name matches one of the configured patterns in `release.config.js`:
+
+- `fix/*` - bug fixes for client distribution
+- `feat/*` - new features for client distribution
+- `beta` - explicit beta channel
+- `master` - production releases
+- Version branches like `1.x` or `1.2.x` - maintenance releases
+
+Note: `chore/*` branches intentionally don't publish as they're for internal changes.
+
+### "npm publish failed with 403"
+
+If using Option A (npm token):
+
+- Verify `NPM_TOKEN` is set in the environment secrets
+- Check the token has publish permissions: `npm token list`
+- Ensure the token hasn't expired
+
+If using Option B (OIDC):
+
+- Verify the GitHub Actions OIDC provider is configured in npm org settings
+- Check that `id-token: write` permission is set in the workflow
+- Ensure `provenance: true` is set in semantic-release npm plugin config
+
+### "Environment branch policy blocking publish"
+
+If you set "Protected branches only" in the environment:
+
+- Make sure your branch pattern is added to the protection rules
+- Or switch to "All branches" and rely on semantic-release filtering
+
+## How It Works
+
+1. **Branch Detection**: When you run the release workflow with `type=beta`, the workflow reads your current branch name
+2. **semantic-release Matching**: semantic-release checks if your branch matches any pattern in `release.config.js`
+3. **Version Calculation**: Based on conventional commits, it determines the next version and appends the prerelease suffix
+4. **npm Publish**: Publishes to npm with the corresponding dist-tag
+5. **GitHub Release**: Creates a GitHub release (marked as prerelease)
+
+## Migrating from Old "Beta" Setup
+
+The old setup used `{ name: '*', prerelease: 'beta' }` which made ALL non-master branches publish as "beta". This was confusing because:
+
+- Fix branches weren't actually beta releases
+- You couldn't have multiple prerelease channels
+- The GitHub environment was called "Publish-Beta" but handled all prereleases
+
+The new setup is more explicit and semantically correct:
+
+- Each branch category gets its own channel
+- The environment is now "Publish-Prerelease" to reflect its broader scope
+- "beta" is now an explicit channel for the `beta` branch only
